Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The E2Pdf – Export Pdf Tool for WordPress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.32.26. This is due to the screen_action() function lacking a dedicated capability check and nonce verification — when invoked via the ?action=screen routing path the controller's index_action() nonce gate is bypassed entirely — while reading an attacker-controlled option name and value from $_POST['wp_screen_options'] and passing them directly to update_option() with no allowlist, relying solely on the page-level e2pdf_templates capability which the plugin's own Permissions UI allows administrators to grant to any role including Subscriber, Contributor, Author, or Editor. This makes it possible for authenticated attackers, with a custom role that has been granted the e2pdf_templates capability, to overwrite arbitrary WordPress options such as default_role and thereby escalate their privileges to administrator.

dbcve analysis · high confidence

The E2Pdf WordPress plugin versions up to 1.32.26 have a Missing Authorization vulnerability in the screen_action() function. When accessed via the ?action=screen routing path, this function bypasses the nonce verification and capability checks present in index_action(). It directly uses attacker-supplied option names and values from $_POST['wp_screen_options'] in update_option() calls without any allowlist, relying only on the e2pdf_templates capability—which the plugin's UI allows administrators to grant to low-privileged roles. This enables authenticated attackers with this capability to modify arbitrary WordPress options like default_role and escalate to administrator.

MitigationUpdate to a patched version immediately. Until then, revoke the e2pdf_templates capability from all roles below Administrator using the WordPress user role editor, or disable the plugin entirely if updates are unavailable.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check E2Pdf plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate E2Pdf, or inspect the plugin main file header for 'Version' value
    Affected if Version is 1.32.26 or lower
  2. Identify roles with e2pdf_templates capability
    Use a WordPress user role editor plugin or query wp_options for custom role capabilities, or inspect the plugin code for add_cap() calls
    Affected if Any role other than Administrator has the e2pdf_templates capability granted
  3. Verify capability assignment source
    Check if an Administrator explicitly granted e2pdf_templates to lower roles via the E2Pdf plugin's role assignment UI
    Affected if Non-Administrator roles were granted e2pdf_templates capability through plugin settings
  4. Audit recent WordPress option changes
    Review wp_options table for recent modifications to sensitive options (default_role, users_can_register, admin_email) or check site logs for update_option calls via wp_screen_options
    Affected if Options were changed without Administrator knowledge or correlate with plugin activity

If E2Pdf version is 1.32.26 or lower AND any non-Administrator role holds the e2pdf_templates capability, the site is vulnerable to privilege escalation via arbitrary option modification.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to a patched version immediately. Until then, revoke the e2pdf_templates capability from all roles below Administrator using the WordPress user role editor, or disable the plugin entirely if updates are unavailable.

Recommended fix Moderate confidence

Plugin version newer than 1.32.26 (check WordPress plugin repository for latest stable release)

  1. 1. Log in to WordPress admin dashboard with administrator privileges
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate the 'E2Pdf – Export Pdf Tool for WordPress' plugin
  4. 4. If an update is available, click 'Update Now' to install the latest version
  5. 5. After updating, navigate to Settings > E2Pdf > Permissions
  6. 6. Review and restrict the 'e2pdf_templates' capability - ensure it is only granted to Administrator role
  7. 7. Verify the update was successful by checking the plugin version (should be newer than 1.32.26)
